David Brock, ally to Hillary, joins Twitter

1/14/14 11:20 AM EST

David Brock, the Media Matters for America founder and public advocate for Hillary Clinton, is joining Twitter, where he plans to continue his campaign against right-wing media and to promote Clinton's bid for the presidency.

"Doing this because I'm a bit old school in the way I consume news and I realize that has to change and Twitter is where it's at," Brock, who has registered under the handle @davidbrockdc, told POLITICO on Tuesday.

Brock's Media Matters, the leading liberal watchdog organization in American politics, has devoted much of its efforts to combating Fox News, Rush Limbaugh, and other key players in the right-wing media. Late last year, it announced plans to develop new technology initiatives, dubbed “Project Metis,” which will track the sources of misinformation throughout the media.

For his first tweet, Brock plans to write: "Wanted to make sure others aren't blinded by the right, so finally joined @twitter. Let the Fun Begin!"

Brock is also the head of American Bridge PAC, which has devoted itself to Clinton's election in 2016. Brock has also served as Clinton's informal attack dog, combating mainstream media organizations -- including NBC, CNN, The New York Times and '60 Minutes' -- wherever and whenever there is even a whiff of anti-Clinton sentiment.

"At this point I'd be remiss not to use such a powerful platform to communicate more widely," Brock said of his decision to join Twitter. "I have a lot of ideas that are too edgy or otherwise not right for the missions of Media Matters or American Bridge, so this is a practical tool for getting them out."

"Also, my new dog is pretty great. Wasn't the Internet invented to share pictures of cute pets?" he added.
